Vacuum Freeze Dryer
Vacuum freeze dryercan keep the original structure of materials from being damaged to the greatest extent, with unchanged biological activity, uniform appearance color, full shape and firm structure, especially for enzyme concentrate, thermosensitive substances and freeze-drying of fruits and vegetables.

Working principle
Vacuum freeze-drying technology is a new drying method, which freezes water-containing materials into solid and dehydrates them at low temperature and pressure by using the sublimation characteristics of water. Because the vacuum freeze-drying technology is carried out in low temperature and low oxygen environment, most of the biological reactions are stagnant, and there is no liquid water in the treatment process. The water sublimates directly in the solid state, so that the original structure and shape of the material are protected to the greatest extent. Finally, high-quality dry products with both appearance and internal quality are obtained, such as medicine, biological products, food, blood products Active substances, etc.
Feature
- The processing capacity can be customized.
- The original structure of the material is not damaged to the greatest extent, the biological activity remains unchanged, the appearance color is uniform, the shape is full, and the structure is firm.
- Low temperature drying, especially for heat sensitive materials.
- The process of freeze-vacuum drying is free from impurity.
- The temperature uniformity and flatness of the thermal conductive layer are good to ensure the uniformity of drying.
